after the guide slide bar 6021 is slidably mounted in the guide slide groove 6011, the wedge-shaped clamping heat conduction block 602 can move in a wedge shape on the wedge-shaped fixed heat conduction block 601, so that the guide performance is better, and the position deviation is not easy to occur;
when the load testing device 2 is used for testing, the box door 12 can be selected to be closed, or the box door 12 can be selected to be opened, when the box door 12 is closed, the box door lock 14 arranged on the box door 12 is locked, when the box door is opened, a key is inserted into the box door lock 14 and is rotated, so that the box door 12 can be opened;
through the water circulation cooling mechanism 7, water circulation can be realized on the protective box 1, so that the load testing equipment 2 is cooled, water can be contained in the water body containing cavities 101, when the water circulation cooling mechanism 7 works, water in one water body containing cavity 101 can be conveyed to the other end of the water circulation cooling mechanism 7 through one end of the water circulation cooling mechanism 7 and then conveyed to the other water body containing cavity 101, when the bidirectional water pump 701 works in the forward direction, the bidirectional water pump 701 can pump water in the water body containing cavity 101 adjacent to the water pumping pipe 702 through the water pumping pipe 702, convey the water to the water conveying pipe 703, and then convey the water to the water body containing cavity 101 adjacent to the water conveying pipe 703 through the water conveying pipe 703;
when the bidirectional water pump 701 works reversely, the bidirectional water pump 701 can pump water in the water body accommodating cavity 101 adjacent to the water conveying pipe 703 through the water conveying pipe 703, convey the water to the water pumping pipe 702, and convey the water to the water body accommodating cavity 101 adjacent to the water pumping pipe 702 through the water pumping pipe 702;
